Ooo that's a hard one. Hearts on Fire is a really good song but i also like Blood Bound and Born to Rule. Man there are a lot of really good songs lol. There's like at least two sweet songs on every album.
At first I kinda thought they were a little weird because I didn't like the singer's voice, but it grew on me and I like them a lot. I like Any Means Necessary because it's epic. And Blood Bound is good too.
First song I heard from them was Hearts On Fire, truly one of their best song. I think it might even be my favourite, but I also really like Blood Bound, Renegade, Restless Soul, Never Ever, Stronger Than All.
